WHEELLALIGNING ADEV ICE.

i Application ined may 14,

This inventionnrelates to `geometricalainstruments and its .general objectV is topravide awwheel aligninggage primarily designedfoiwaligning-the wheels ofamotor vehicle andthe like inwan veflicientand expeditiousmanner and ywith very little effort on the 'part oftheoperator.

Another object of `the-invention is to providea :wheel laligning y'gagel that fis capable of. f being operated with.-.extreme accuracy, withVthe result that correct v and positive gaging as well as proper.alignment-of the wheelswill be assured.

Afurther objectzof Vthe invention isv to vprovide a. fVehicle wheel.aligning tool-that-is capable of adjustmentso-that it can-bereadily1used on all types of Avehicle-wheels, is simple invconstruction, contains few parts, and is inexpensive to .manufacturerThisinvention :also consi-sts in certain othervfeatures 'oficonstruction and in the combination and arrangement of the `severalparts,l to be hereinafter fully-described, illustrat'edin the Yaccompanying drawings and specifically pointed outinthe-appendedclaims.v

' In'descrifbing'our inventionfin detail, reference'will? be had `to\the' accompanying drawings whereinlike characters denote likeorcorresponding-parts.vthroughout the severall views, and infwhich:

Referring to the drawings in detail the reference numeral 1 indicatesthe body of the gage and which as shown in Figure 1. is formed intubular formation and has one end bent at right angles to provide anupright portion 2. Extending from adjacent the opposite ends of thehorizontal portion of the body are feet 3 whichv support and elevate thebody a suitable .distance as shown in Figure 1 of the drawings.V

Telescopically mounted within the horizontal portion of the body is onearm 4 of a. substantially right angle shaped member 5 which has itsother arm indicated by the reference numeral 6 and is hollow for theheight, 4while the set screw '18 is threadedly secured' in y.the body 1and isadapted4 `for clamping the-member -5 in any 1 desired .adjustedposition with respectto the body..y

4-lvlounted for vertical adjustable movement in theupri-ght Ziseacstem1f1'which is 1 likewise provided -witha 'longitudinal groove 15 as :wellas recesses not shownto accommodate a-set1screw 16."`

The stem` has `integrallyfformed. Iwith (or otherwise'securedto itsupper endfa Sleeve 17'l slidably receivingv a -rodA 18 'which isythreaded for a portionof its length as at-l9 to receivef a 'flangedadjusting nutnZOy v'having serrations von its outerl surface to provide:a positive `ringer engaging means. n In order toy limit the slidablemovementof the rod 18, through the sleeve- 17 the rod' has lsecuredadjacent its opposite 4ends the parallel arms-21 of asubstantially1-Ushapedselonf gated vmember 22 which has formedon theouter face of `itsfbight portiongraduations 23 whichcooperate-withvapointer 24 formed integral with or f otherwise Secured to one endof thesleeve 17.- The-rod^18 is adjustablethroughthe-sleeve by rotation of.the

nut .20 `as willl be apparent-,- and. onexend of the rodiisfreduced asat andthis reduced f portion... terminates in av pointed endf`26 whichvcooperates with the point 9 of the member 8 when aligning the wheels.Surn rounding the rod 18 and having its end convolutions engaging oneend of thesleeve 17 and the adjacent arm 21 of the substantiallyU-shaped member 22 is a coil spring 27 which disposes the sleeve incontacting .engagement with the nut 20 as best shown in Figure 3 of thedrawings.`V

From the above description and disclosure of the drawings, it will beobvious that the wheel aligning gage which forms the subject matter ofthe present invention is capable of adjustment for all type vehicles andwill perform its intended function in an efficient and accurate mannerwith very little effort on the part oi' the operator. To properly alignthe Wheels of a vehicle, the tool is disposed between the Wheels asshown in Figure l of the drawings and the member 8 and shank 14 areadjusted to their proper height. The point 9 is disposed in contactingengagement With the elly of the adjacent wheel as shown, and the nut 20is rotated on the threads ot' the rod 19 until the desired distance isreached which can be readily seen upon inspection oi the pointer 24 withrespect tothe graduations 23, With the result the condition of theWheels can Y be ascertained at a glance and corrected if necessary.

It is thought from the foregoing description that the advantages andnovel features of our invention will be readily apparent.

`We desire it to be understood that we may make changes in theconstruction and in the combination and arrangement of the severalparts, provided that such changes fall Wit-hin the scope of the appendedclaims.

What we claim is:

1'. A Wheel aligning gage of the character described comprising atubular body, feet depending therefrom tor supporting the same, atubular upright formed with one end of said body, a right angle shapedmember telescopically mounted in the opposite end oi the body, means foradjustably securing said member with respect to said body, a pointedmember including a shank mounted Jfor vertical adjustment in said rightangle disposed member, a sleeve mounted for vertical adjustment in saidtubular upright, a threaded rod slida-ble through said sleeve andterminating at one end in a point adapted to cooperate With the point ofthe pointed member, a nut carried by said threaded rod, and resilientmeans for retaining said nut in contacting engagement With one end ofsaid sleeve for the purpose specied.

2. A gage of the character described comprising a tubular body, anupright formed therewith, a sleeve having a shank received in saidupright for adjustable movement therein, a rod having a threaded portionand mounted for slidable movement through said sleeve, a substantiallyU-shaped elongated member having its arms ixed adjacent the ends of saidrod to limit movement of said rod through said sleeve, a nut carried bythe threaded portion of said rod :tor adjusting the same through thesleeve, resilient means for retaining said nut in contacting engagementwith said sleeve, said rod having a pointed end, and means cooperatingWith said pointed end and carried by said body for aligning the Wheelsof a vehicle.

3. A gag-e of the character described comprising a body, meanstelescopically mounted in one end of said body, pointed means adjustablyassociated with the first mentioned means, an upright formed with saidbody, a sleeve, a shank formed with said sleeve and being telescopicallymounted in the upright tor cooperative adjustment with said pointedmeans, a rod mounted for slidable movement through said sleeve andprovided With a threaded portion, a substantially elongated Ushapedmember having its arms fixed adjacent the ends of the rod, and beingprovided with graduations on its face, a nut carried by the threadedportion oi' said rod for moving the rod through said sleeve, a coilspring surrounding said rod for retaining said nut in operativeposition, a pointer carried by said sleeve and cooperating With saidgraduations and said rod having its outer end pointed for cooperationWith said pointed member for aligning the Wheels of a vehicle.

4., A wheel aligning gage of the character described comprising a body,feet for said body, means adjustable longitudinally in one end of saidbody and including a hollow portion, a pointed member mounted Jforadjustment in said means, an upright formed with the opposite end ofsaid body, a sleeve, .a stem depending from said sleeve and mounted foradjustment in said upright, and pointed means adjustably mounted in saidsleeve and cooperating with the pointed member as and for the purposespecified.
